I make films, photographs and electronic music. I build electronic musical instruments

  • CGS Wave Multipliers module completed

    Finally, after being in my backlog for more than a year, I finished the CGS Wave Multipliers module today. This module contains three separate wave folders (a Serge-like wave folder, a Lockhart “Nonselective Frequency Tripler”, a simple multiplier and a ring modulator. It’s a great module which can produce some very interesting timbres. I got…

  • Studio acoustics (part 1)

    While working on a new track some time ago I switched from listening over the near-field monitors to my headphone. I was in for a very unpleasant surprise. It was a track with some fast sequencing and delay effects. Through the headphones everything sounded fine but through the monitor speakers the sound became… blurry. It’s…

  • Jean-Michel Jarre live in Ahoy, Rotterdam

    With a couple of friends I went to a concert of Jean-Michel Jarre in Ahoy, Rotterdam (Netherlands). For me it was pure nostalgia. Jarre being one of the first electronic music artists I was exposed to (the first one was Vangelis with “Spiral” which was played by a rather open minded music teacher in High…

  • Screenplay for a short movie

    I finished a screenplay for a short film I want to make. It’s about a young woman having a strange meeting in a park which makes her think what it is she really wants. The story has a bit of a Twilight Zone atmosphere to it. The screenplay is 10 pages long which translates in…

  • Crafting short screenplays that connect

    I read an interesting book about writing short screenplays. It’s “Crafting short screenplays that connect – 2nd edition” by Claudia Hunter Johnson. Books about writing screenplays always talk about conflict. There has to be some form of conflict (that may be physical or emotional or any other form of conflict) in a story to be…

  • Nikon AIS 50-135mm f3.5

    I found this great constant aperture manual zoom lens on eBay for a very good price. It has some specks of dust in the lens so that prevented a lot of people from bidding on it I guess. It was a bit of a gamble but I really like the lens. And, the few specks…

  • First green screen experiment

    I received a portable green screen today and did a quick test using my daughter as the subject. As she loves to play princess she dressed up and it was my task to put her in front of that cool castle 😉 I took some shots of her in front of the green screen using…

  • Skate wheel dolly Mk2

    I modified my initial skate wheel dolly so it would be *much* lighter and more portable. The old dolly is heavy and takes up quite some space and therefore also needs quite some space to transport and store. I got the idea when reading a blog post by Ryan E. Walters. He also converted a…

  • The building of an instrument

    My modular consists of a fair amount of modules at the moment. I took about a year and a half to built. I built everything myself except for the front panels and the printed circuit boards. Here’s a picture of the current configuration. As you can see there is still some room in the top…

  • The Klee v2 analog sequencer (part 5)

    After 2 months of building and 1 week of debugging… It’s DONE! I finished debugging and calibrating the Klee sequencer today. It has been quite an experience, the most complex module I build so far. Lots of front panel components, lots of wiring. I must compliment Scott Stites for writing such an excellent construction manual.…

  • The Klee v2 analog sequencer (part 4)

    Almost done! Just a few interconnect wires and then it’s completed.

  • The Klee v2 analog sequencer (part 3)

    I finished wiring the digital PCB of the Klee sequencer today. The loose wires you see in the picture below are the interconnect wires which will connect the digital PCB and the analog PCB together. This is a lot of work, but it’s fun. I must restrain myself though from working on it when it’s…
